Lead-acid batteries are widely used in all walks of life because of their excellent characteristics, but they are also facing problems such as the difficulty of estimating electricity and the difficulty of balancing batteries.

If current is being provided to the battery faster than lead sulfate can be converted, then gassing begins before all the lead sulfate is converted, that is, before the battery is fully charged. Gassing introduces several problems into a lead acid battery. Not only does the gassing of the battery raise safety concerns, due to the explosive

Lead–acid batteries are comprised of a lead-dioxide cathode, a sponge metallic lead anode, and a sulfuric acid solution electrolyte. The widespread applications of lead–acid batteries include, among others, the traction, starting, lighting, and ignition in vehicles, called SLI batteries and stationary batteries for uninterruptable power supplies and PV systems.
Positive plate limited capacity degraration of a lead acid battery is reviewed. It suggested that the capacity loss of a battery is related to quality degradation of its positive active mass. Capacity degradation is represented by a shift in Peukert line (Iog t vs log I) and is related to the changes in the active mass morphology as a function

When stored, SLA batteries undergo two main degradation processes: self-discharge and sulfation. Self-discharge occurs due to internal chemical reactions, leading to gradual loss of charge over time. Sulfation, a more pronounced issue, arises from the accumulation of lead sulfate crystals on the battery plates.

The lead acid battery technology has undergone several modifications in the recent past, in particular, the electrode grid composition, oxide paste recipe with incorporation of foreign additives into the electrodes and similarly additives added in the electrolytes to improve electrical performance of the lead acid battery.
On the other hand, at very high acid concentrations, service life also decreases, in particular due to higher rates of self-discharge, due to gas evolution, and increased danger of sulfation of the active material. 1. Introduction The lead–acid battery is an old system, and its aging processes have been thoroughly investigated.
Considered a mature and initial low cost technology, lead-acid battery technology is well understood and found in a wide range of photovoltaic (PV) energy storage applications. For this reason, the researchers are very concerned by the study of degradation mechanisms affecting the battery lifetime.
Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.
The anodic corrosion, positive active mass degradation and loss of adherence to the grid, irreversible formation of lead sulfate in the active mass, short circuits and loss of water are the major aging processes. The overcharge of the battery lead to accelerated corrosion and also to accelerated loss of water.
In this role the lead acid battery provides short bursts of high current and should ideally be discharged to a maximum of 20% depth of discharge and operate at ~20°C, to ensure a good cycle life, about 1500 cycles orthree to five years of operation .
